Atm pet is not good only for it's dmg, but it's a tool that get's us more fury, so we have enough for the next DS. After we will drop 4PC set T14, we will have DS at 2 min instead of 1.33, so perhaps we could live with slower fury regen? Also 4pc (10% more fury gain from abilities could cover pet loss).

Just a theory, but I hope I'm wrong here, and we won't see demo with Gosac, it's just wrong.
